Benefits of technology

[0011] An advantage of the present invention is that the pet door is opened based upon the identification of an approaching animal and still maintains a weather resistant inner barrier to the weather until the pet overcomes the seal of the inner flexible door in order to enter the home.
[0012] Another advantage of the present invention is that as soon as the pet is in, the inner door closes and the outer door closes, thereby creating an insulative space therebetween.

Problems solved by technology

The flap is non-insulated and can be very uneconomical during inclement weather.

Embodiment Construction

[0020] Referring now to the drawings, and, more particularly to FIGS. 1 and 2 there is shown a pet door assembly 10 including an inner frame 12, an outer frame 14, a door assembly 16, a control assembly 18, a power source 20 and a door flap 22. Inner frame 12 and outer frame 14 are mounted on opposite sides of a door or wall and extend beyond the opening therein. Inner frame 12 and outer frame 14 are fastened together through the intervening structure by way of screws or other fasteners.

[0021] Door assembly 16 includes slats 24, a roller tube 26, a motor 28, tracks 30, and a brush seal 32. Slats 24 are linked together in a rolling manner along the edges of each slat 24. Slats 24 are interconnected yet are able to be wound around roller tube 26. As shown in FIGS. 3 and 4, slats 24 have a cross sectional shape with a hollow interior defining a thermally insulative air gap. Motor 28 is connected to roller tube 26, which supplies power for the rotation of roller tube 26 to thereby wind...

This sort of pet door offers little or no security, allowing other animals or even people to have access to the home. [0006] Pet doors available on the market today often consist of a soft plastic or aluminum material, which hang by gravity, typi...
